As the second-generation natural antioxidants, grape seed and grape skin extract stay to see stable market. America and Canada are still the major importers. Owing to stable raw material supply and mature extraction technology, the cost of raw material and technology make no large effect on the extracts' prices. The raw material mainly source from Shandong, Xinjiang province and Ningxia Hui Autonomous Region. Besides domestic resource, manufacturers gradually import grape seeds for production.
Main specifications include grape seed extract with polyphenol level at 90 percent or OPC level at 95 percent; grape skin extract with polyphenol level at 10 and 30 percent or OPC level at 5 and 10 percent. As the antioxidant capacity depends on oligomer's activity, the higher activity for oligomer, the higher antioxidant capacity for grape seed extract. Some international clients also pay attention to the antioxidant capacity of grape seed extract. There are not many manufacturers of grape seed extract, and most of them have annual output of 10 to 15 tons. Shijiazhuang Jianhe Biotech concentrates on the extract's production. After process improvement, its annual production capacity increased to 60 tons from 40 tons this year. The antioxidant capacity of its grape seed extract is tested at 16000-18000 umol TE/G by Brunswick Lab.
The grape extract market will probably run steady in the future.
